TECHNICAL FIELD
[0001] The present application relates to the technical field of offshore engineering equipment, in particular to a magnetic wind power pile foundation attached organism hanging plate device. BACKGROUND
[0002] With the rapid development of offshore wind power industry, the wind power pile foundation as an important support structure of offshore wind turbine is long-term in the marine environment. A large number of marine organisms will be attached to the surface of the pile foundation, which will not only affect the structural integrity and durability of the pile foundation, but also may have some impact on the surrounding marine ecological environment. In order to study the species, quantity, growth rate and distribution of the attached organisms, so as to take corresponding protection and ecological control measures, an effective monitoring device is needed; among them, the hanging plate as an important carrier for monitoring the attached organisms, its connection mode and device design are very important.
[0003] The existing hanging plate connecting assembly is mainly divided into fixed type and clamping type; the fixed type connecting assembly commonly includes welding fixation and bolt fixation and the like, and such fixed type is easy to cause damage to the pile foundation column body, and in order to avoid damage to the pile foundation, the clamping type is usually adopted; the clamping type connecting assembly fixes the hanging plate on the pile foundation through a clamping rod, and its working principle is to exert a certain pre-pressure on the clamping rod, and to use the friction force to ensure the stable installation of the hanging plate.
[0004] However, the clamping type connection mode also has some problems to be solved. Since seawater is a kind of environment containing high-concentration chlorine ions, oxygen and other strong corrosive media, when the pre-pressure exerted by the clamping rod makes the metal material in a continuous tensile stress state, the combination of the two may cause stress corrosion cracking. Stress corrosion cracking is a brittle fracture phenomenon produced under the combined action of a specific corrosion environment and tensile stress, and its characteristics are fast crack propagation speed, which often leads to sudden failure of the structure without obvious premonition. When the pre-pressure exceeds the critical value, the cracking speed will be rapidly accelerated with the increase of the stress, which seriously affects the service life of the clamping rod and the installation stability of the hanging plate. If the pre-pressure is insufficient, it cannot provide enough friction force to fix the position of the hanging plate, and under the action of water flow, wave and other dynamics in the marine environment, the position of the hanging plate is easy to change or even fall off, thereby affecting the accuracy and reliability of the attached organism monitoring. SUMMARY

The movable sleeve is rotatably arranged relative to the shell. The clamping rods are arranged in pairs and are respectively installed on the shell and the movable sleeve. The movable sleeve is rotatable relative to the shell, the spacing of the clamping rods is adjusted, and the pile foundation is clamped. The shell is fixed with the lower support rod through the connecting rod. The sliding shaft is axially slidably arranged on the shell through the flat key, and the side wall is provided with a guide shaft; one end of the sliding shaft towards the electromagnet is provided with a permanent magnet, and the electromagnet can drive the sliding shaft to move axially through the permanent magnet. The shaft sleeve is rotatably arranged relative to the shell, and the inner wall of the shaft sleeve is provided with a wedge-shaped groove in sliding fit with the guide shaft. The elastic member is arranged between the shaft sleeve and the movable sleeve at both ends. The one-way position limiter is installed between the shell and the shaft sleeve, and is used for limiting the one-way rotation of the shaft sleeve. The conical block is elastically slidably arranged in the sliding shaft through the spring, and the inclined surface abuts against the guide shaft. The electromagnet attracts the permanent magnet, so that when the sliding shaft axially displaces, the guide shaft drives the shaft sleeve to rotate through the wedge-shaped groove, the shaft sleeve rotates and compresses the elastic member, and the other end of the elastic member increases the pre-pressure of the corresponding clamping rod through the movable sleeve; when the pre-pressure reaches the preset value, the guide shaft overcomes the pressure of the conical block and separates from the wedge-shaped groove, the one-way position limiter limits the reverse rotation of the shaft sleeve, and the pre-pressure of the clamping rod is maintained.
[0007] As a further scheme of the present application, an adjusting plate is axially slidably arranged in the sliding shaft, the adjusting plate is threadedly connected with an adjusting rod, the adjusting rod is rotatably arranged on the sliding shaft, and the adjusting plate is connected with the conical block through the spring.
[0008] As a further scheme of the present application, the positioning member is arranged on each of the clamping rod and the lower support rod.
[0009] As a further scheme of the present application, the one-way position limiter comprises: The fixed disc is axially slidably arranged on the shell, and the side wall of the fixed disc is provided with a fixed tooth of trapezoidal structure; The movable disc is fixed with the shaft sleeve, the side wall of the movable disc is provided with a movable tooth of trapezoidal structure, and the adjacent ends of the movable tooth and the fixed tooth are direct edges and inclined edges, respectively. A spring plate is installed between the fixed plate and the housing.
[0010] As a further embodiment of the present invention, the frame includes uprights mounted on clamping rods, with horizontal bars rotatably mounted at both ends of the uprights via telescopic components. Fixing bolts are installed between the horizontal bars and the telescopic components, and connecting arms are installed between the horizontal bars for mounting hanging plates.
[0011] As a further embodiment of the present invention, the angle adjustment assembly includes an adjustment shaft, the end of which passes through a connecting arm and is threadedly connected to a fastening nut, and the adjustment shaft is inserted into a mounting shaft fixed to a hanging plate, the mounting shaft being fixed to the adjustment shaft by a nut.

An encoding plate is inserted into the encoding frame, and a fixing magnet for fixing the encoding frame is installed in the installation groove.
[0013] As a further aspect of the present invention, the mounting plate is provided with a plurality of evenly distributed through holes.
[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, during the clamping process, the preload of the clamping rod is precisely controlled through the synergistic action of components such as the electromagnet, permanent magnet, sliding shaft, guide shaft, bushing, and elastic element. When the clamping rod contacts the pile foundation, as the sliding shaft continues to displace, the elastic element gradually stores force, and the preload gradually increases. When the preset range is reached, the wedge groove disengages from the guide shaft, and the bushing is restricted from reverse rotation by a one-way limiter, thus maintaining the preload within the preset range. This avoids stress corrosion cracking caused by excessive preload placing the metal material under continuous tensile stress, effectively extending the service life of the clamping components and reducing maintenance costs. It also provides a stable and reliable preload, ensuring the hanging plate is firmly installed in the marine environment. Under the dynamic action of seawater currents and waves, the hanging plate will not change position or fall due to insufficient preload, ensuring the accuracy and reliability of attached organism monitoring. This provides a stable and reliable monitoring platform for studying the types, quantities, growth rates, and distribution patterns of attached organisms, and helps to take more effective protection and ecological regulation measures.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-11The present invention provides a technical solution: a magnetic wind power pile foundation attachment biological hanging plate device, including a frame 1, a plurality of angle-adjustable hanging plates 3 are installed on the frame 1 by an angle adjustment component 2, and a clamping component 4 for suspending the frame 1 on the pile foundation is installed on the frame 1. The frame 1 is installed on the pile foundation by the clamping component 4, and the angle of the hanging plates 3 is adjusted by the angle adjustment component 2. Clamping component 4 includes: A housing 41 is mounted on the frame 1, and an electromagnet 42 is installed inside the housing 41; The movable sleeve 43 is rotatably mounted relative to the housing 41; The clamping rods 44 are arranged in pairs and are respectively installed on the housing 41 and the movable sleeve 43; The movable sleeve 43 rotates relative to the shell 41 to adjust the spacing of the clamping rods 44 and clamp the pile foundation. The housing 41 is fixedly provided with a lower support rod 45 via a connecting rod; The sliding shaft 47 is axially slidably mounted on the housing 41 via a flat key, and a guide shaft 48 is provided on the side wall; a permanent magnet 49 is mounted on the end of the sliding shaft 47 facing the electromagnet, and the electromagnet 42 can drive the sliding shaft 47 to move axially through the permanent magnet 49. The bushing 6 is rotatably disposed relative to the housing 41, and the inner wall of the bushing 6 is provided with a wedge-shaped groove 61 that slides with the guide shaft 48; The elastic element 62 is disposed at both ends between the bushing 6 and the movable sleeve 43; One-way limiter 7 is installed between housing 41 and bushing 6 to limit the one-way rotation of bushing 6; The conical block 53 is elastically slidably disposed inside the slide shaft 47 by a spring, and its inclined surface abuts against the guide shaft 48; When the electromagnet 42 attracts the permanent magnet 49, causing the sliding shaft 47 to move axially, the guide shaft 48 drives the bushing 6 to rotate through the wedge groove 61. The rotation of the bushing 6 compresses the elastic element 62, and the other end of the elastic element 62 increases the preload of the corresponding clamping rod 44 through the movable sleeve 43. When the preload reaches the preset value, the guide shaft 48 overcomes the pressure of the cone block 53 and disengages from the wedge groove 61. The one-way limiter 7 restricts the bushing 6 to rotate in the opposite direction, so that the preload of the clamping rod 44 is maintained. When installing the biological monitoring hanging plate connection device for offshore wind power pile foundation, first place the clamping rod 44 securely on both sides of the pile foundation, and ensure that the lower support rod 45 and the clamping rod 44 on the same side are tightly attached to the surface of the pile foundation, so as to prepare for subsequent stable clamping. Subsequently, the electromagnet 42 is energized to put it into working condition; after the electromagnet 42 is energized, it will generate an attractive force on the permanent magnet 49; under the action of this attractive force, the sliding shaft 47, which is fixedly connected to the permanent magnet 49, will be displaced along the axial direction of the housing 41; the movement of the sliding shaft 47 will drive the guide shaft 48 to move synchronously, and during the movement, the guide shaft 48 will drive the bushing 6 to rotate around its own axis through the interaction with the wedge groove 61; when the bushing 6 rotates, it will drive the movable sleeve 43 to rotate with the help of the elastic element 62. The movable sleeve 43 drives the clamping rod 44 fixed thereto to rotate. The clamping rod 44 gets closer to the pile foundation, and the distance between the two clamping rods 44 continuously shortens, eventually achieving the initial clamping action on the pile foundation. After both clamping rods 44 have contacted the pile foundation, the sliding shaft 47 continues to move; at this time, the bushing 6 also continues to rotate; however, since the clamping rods 44 installed on the movable sleeve 43 have already contacted the pile foundation, they are unable to continue rotating due to the obstruction of the pile foundation, causing the movable sleeve 43 to be unable to continue rotating under the drive of the elastic element 62; in this case, the bushing 6 can only rotate relative to the movable sleeve 43, and this relative rotation causes the elastic element 62 to be gradually compressed and store force; as the degree of force stored by the elastic element 62 increases, its preload on the movable sleeve 43 also gradually increases, and this preload directly reacts with the elastic element 62. As the preload of the clamping rod 44 on the pile foundation gradually increases, the reverse force exerted by the wedge groove 61 on the guide shaft 48 also gradually increases, causing the guide shaft 48 to gradually move inward toward the sliding shaft 47. When the preload of the clamping rod 44 on the pile foundation reaches the preset range, the wedge groove 61 and the guide shaft 48 just disengage. At this time, the bushing 6 is restricted by the one-way limiter 7 and cannot rotate in the reverse direction, thus ensuring that the preload of the elastic element 62 on the movable sleeve 43 can be stably maintained, thereby keeping the preload of the clamping rod 44 on the pile foundation always within the preset reasonable range. When the permanent magnet 49 moves to contact the electromagnet 42, the sliding shaft 47 stops moving, and then the electromagnet 42 is de-energized, causing it to stop working. At this point, the clamping rod 44 has completed the stable clamping of the pile foundation, ensuring that the frame 1 remains stable and that the hanging plate 3 is fixed relative to the pile foundation.
[0020] During the above process, the reverse force generated by the elastic element 62 on the bushing 6 is cleverly transmitted to the sliding shaft 47 through the wedge groove 61 and the guide shaft 48, and the shell 41 is kept in a certain rotational tendency by the flat key. In order to prevent the clamping rod 44 installed on the shell 41 from moving away from the pile foundation during the force process, a lower support rod 45 is specially added. The lower support rod 45 effectively restricts the rotation of the shell 41 by closely contacting the pile foundation, thereby ensuring the stability of the entire clamping rod 44 clamping device.
[0021] In summary, unlike existing fixed connection components (such as welding and bolting), this device uses a clamping method to fix the hanging plate 3 to the pile foundation. There is no need to weld or drill the pile foundation, which will not cause structural damage to the pile foundation column, ensuring the integrity and safety of the pile foundation and facilitating the long-term stable operation of offshore wind turbines.
[0022] During the clamping process, the preload of the clamping rod 44 is precisely controlled through the coordinated action of components such as the electromagnet 42, permanent magnet 49, sliding shaft 47, guide shaft 48, bushing 6, and elastic element 62. When the clamping rod 44 contacts the pile foundation, as the sliding shaft 47 continues to move, the elastic element 62 gradually stores force, and the preload gradually increases. When it reaches the preset range, the wedge groove 61 disengages from the guide shaft 48, and the bushing 6 is restricted from rotating in the opposite direction by the one-way limiter 7, thus maintaining the preload within the preset range. This prevents the metal material from being subjected to excessive preload. The stress corrosion cracking problem caused by tensile stress effectively extends the service life of the clamping component 4 and reduces maintenance costs; it can also provide stable and reliable pre-pressure to ensure that the hanging plate 3 is firmly installed in the marine environment; under the dynamic action of seawater currents, waves and other forces, the hanging plate 3 will not change position or fall off due to insufficient pre-pressure, ensuring the accuracy and reliability of attached organism monitoring, providing a stable and reliable monitoring platform for studying the types, quantities, growth rates and distribution patterns of attached organisms, and helping to take more effective protection and ecological regulation measures.
[0023] As a further embodiment of the present invention, an adjusting plate 51 is axially slidably disposed inside the sliding shaft 47, and an adjusting rod 52 is threadedly connected to the adjusting plate 51. The adjusting rod 52 is rotatably disposed on the sliding shaft 47, and the adjusting plate 51 is connected to the conical block 53 by a spring. For details, see Figure 3 Rotating the adjusting rod 52 causes the adjusting plate 51, which is threaded to it, to move axially along the sliding shaft 47. The distance between the adjusting plate 51 and the conical block 53 changes, and the degree of spring compression between them changes accordingly. The pressure applied by the spring to the conical block 53 changes, which changes the resistance of the guide shaft 48 moving into the sliding shaft 47. This adjusts the time it takes for the guide shaft 48 to disengage from the wedge groove 61, thereby changing the force stored in the elastic element 62. This allows the preload of the clamping assembly 4 to be adjusted according to the roughness of the pile foundation surface and the growth rate of the attachments on the hanging plate 3, thus extending the service life of the clamping assembly 4.
[0024] As a further embodiment of the present invention, each clamping rod 44 and lower support rod 45 is equipped with a positioning element 46, and each positioning element 46 is provided with a fastening bolt; this facilitates the adjustment of the position of the positioning element 46, and the positioning element 46 enables the clamping rod 44 to clamp pile foundations of different shapes. As a further aspect of the present invention, the one-way limiter 7 includes: The fixed disk 71 is axially slidably mounted on the housing 41, and the side wall of the fixed disk 71 is provided with a trapezoidal fixed tooth 72. The movable disk 73 is fixedly mounted to the bushing 6. The side wall of the movable disk 73 is provided with a trapezoidal movable tooth 74. The adjacent ends of the movable tooth 74 and the fixed tooth 72 are a straight edge and a beveled edge, respectively. Spring plate 75 is installed between fixed plate 71 and housing 41; Specifically, when the bushing 6 starts to rotate, the movable disk 73 connected to it will rotate synchronously. During the rotation of the movable disk 73, the movable teeth 74 on it will apply a squeezing force to the fixed teeth 72 on the fixed disk 71 with the help of the inclined edge, causing the fixed disk 71 to move axially and compress the spring plate 75 connected to it. As the movable disk 73 continues to rotate, the movable teeth 74 smoothly pass over the fixed teeth 72. In this way, the movable disk 73 can rotate continuously relative to the fixed disk 71. After the bushing 6 stops rotating, the compressed spring plate 75 will push the fixed disk 71 back to its original position with its own elastic restoring force. This mechanism effectively prevents the bushing 6 from rotating in the opposite direction and ensures that the elastic element 62 can always maintain a constant stored force.
[0025] Furthermore, when it is necessary to disassemble the clamping assembly 4, the fixed plate 71 can be manually driven to displace it, so that the fixed teeth 72 and the movable plate 73 are disengaged. The restriction originally caused by the interaction between the fixed teeth 72 and the movable teeth 74 is removed, and the force can be released from the elastic element 62, which greatly facilitates the disassembly of the clamping assembly 4.
[0026] As a further embodiment of the present invention, the frame 1 includes uprights 14 mounted on clamping rods 44. Both ends of the uprights 14 are rotatably connected to crossbars 12 via telescopic members 11. Fixing bolts are installed between the crossbars 12 and the telescopic members 11. Connecting arms 13 are installed between the crossbars 12 for mounting hanging plates 3. The telescopic members 11 can adjust the distance between the crossbars 12 and the pile foundation, thereby adjusting the distance between the hanging plates 3 and the pile foundation. The crossbars 12 can rotate relative to the telescopic end of the telescopic members 11 and are fixed by fixing bolts, allowing the crossbars 12 to tilt, gradually increasing the distance between the hanging plates 3 and the pile foundation. Different micro-ecological environments are formed at different distances from the pile foundation; detecting the attachments at these locations can reveal the spatial distribution characteristics of the ecosystem. This facilitates early protection of the pile foundation.
[0027] As a further embodiment of the present invention, the angle adjustment assembly 2 includes an adjustment shaft 21, the end of which passes through the connecting arm 13 and is threadedly connected to a fastening nut 22. The adjustment shaft 21 is inserted into a mounting shaft 23 fixed to the hanging plate 3, and the mounting shaft 23 is fixed to the adjustment shaft 21 by a nut; thus facilitating the adjustment of the angle of the hanging plate 3.
[0028] As a further embodiment of the present invention, the side wall of the hanging plate 3 is provided with an installation groove 31, and an encoding frame 32 is rotatably arranged in the installation groove 31 through a sliding groove. An encoding plate 33 is inserted into the encoding frame 32, and a fixing magnet 34 for fixing the encoding frame 32 is installed in the installation groove 31. For details, see Figure 11 The encoding frame 32 can slide along the mounting groove 31. When it slides to the end away from the fixed magnet 34, the encoding frame 32 can be rotated, and the encoding plate 33 can be slid along the encoding frame 32 to remove the encoding plate 33, making it convenient to replace the encoding plate 33. When the outer end of the encoding frame 32 is rotated into the mounting groove 31 and contacts the fixed magnet 34, the encoding plate 33 can be fixed in the mounting groove 31, preventing marine organisms from attaching to the encoding plate 33 and making the encoding on the encoding plate 33 unreadable.
[0029] As a further aspect of the present invention, the hanging plate 3 has a plurality of evenly distributed through holes 35; the through holes 35 can increase the surface area of the hanging plate 3, and at the same time promote the flow of seawater around the hanging plate 3, providing more nutrients and oxygen for the attached organisms.
